Objectives
Narrative objectives1
To prevent oral candidiasis, we aimed to clarify whether continuous intake of food containing the lactic acid bacterium Lactobacillus salivarius WB21 (WB21), which has been shown to inhibit the growth of Candida albicans in in vitro studies, inhibits the growth of Candida in the oral cavity of elderly people who have Candida in their oral cavity, and thus inhibits the onset of oral candidiasis.
